16 Claims.

This invention relates to textile strand manipulating machines which contain traveling winding devices capable, during their traveling motion, of winding strands into headless self-sus- 5 taining cross-wound packages. The wound packages of the class with which this invention is especially concerned possess certain characteristic features, of which may be mentioned: the lay of the strand in the form of reversed spirals each of which extends a plurality of turns around the package and then merges (usually at the end face of the package) into the next spiral portion of opposite direction; the inclination of the spiral portions of winding at sufficient angularity to the axis of the package to cause each spiral portion of winding to cross and bind down a large number of other oppositely directed spiral portions; and usually also the straightness of periphery of the individual wound layers such 20 as is obtained in winding the package into the formof a cylinder or cone. My Patent No. 1,- 609,639 discloses and claims a machine capable of winding such a package during traveling motion of the package in relation to the machine; the present invention is in some respects an improvement upon the invention of that patent.

One object of the present invention is to provide a machine adapted to wind a strand on a traveling strand package (or core therefor) 30 in the form of overlapped reversed spirals each extending a plurality of turns around the package and so disposed with respect to each other that spiral portions of the resulting package lie at approximately constant distances apart, measured peripherally of the layer of which these spiral portions form a part. As a special and preferred case, each right hand spiral of the winding may lie close beside the previously laid right hand spiral, and each left hand spiral 40 close beside the previously laid left hand spiral.

' Such close laying of the reversed spiral windings,

which necessitates consecutive like spirals being laid approximately parallel, results in a package of the maximum density compatible with cross or quick-traverse winding. 'In a broader aspect, my invention provides for laying quickpitch multi-turn spirals on a traveling cheeseor cone in such a way that the ratio between the linear rate of traverse and the linear surface speed of the winding package varies in response to the angular velocity of the winding package. My invention further aims to provide a machine as described above wherein this ratio of linear strand-traverse to linear surfacespeed of package rotation diminishes in accordance with growth of the package. One desirable effect of this is the approximate maintenance through various diameters of the winding cheese or cone of the spacing initially established between successive like spiral portions of the winding, or the close side-by-side placing of the successive like spiral portions if the strand is being closely laid. As a specific and preferred instance, my invention provides in a traveling winding machine adapted to lay the strand in the formation of alternate right and left-hand spirals or helices each extending a plurality of times around the package, means whereby the rate of traverse may be diminished directly in proportion to increase of diameter of the growing package and be made to bear a constant ratio to the angular velocity of the growing package, this ratio being such as to lay each successive like spiral portion of the winding close beside the previously laid like spiral portion.

Another object of the invention is to provide, particularly in a winding machine wherein the winding package is rotated by frictional contact with a drive' roll, a traverse guide adapted to work on the surface of the winding package so as to lay the winding strand accurately in place; an additional object is to accomplish this by a compactly constructed traverse guide capable of operating eifectively at high speeds, or. capable of participating in the motion of the circulating winding packages of a traveling winding'machine, such as that of the above patent.

A further object of the invention is to provide a method of and apparatus for winding characterized by initial rotation of the winding package by torque applied to the interior of the package, and subsequent rotation of the winding package by torque applied to the periphery of the package. Other objects of invention improvements and novel features will be apparent from a consideration of this specification and its drawings wherein illustrative examples of my invention are explained.

Referring to Figs. 1, 2 and 3, the illustrated machine includes in common with the machines of vmy above patent, the patent of E. J. and W. G. Abbott, No. 1,700,425, and of my application, Serial No. 476,776, a continuous guideway constituted of upper and lower rails 4 and 5 supported by suitable frame members and defining a closed path of circulation for a large number of winding carriers along opposite straight and semi-circularruns. Suitable means for moving the carriers along the guideway may include an endless chain 30 running on sprockets 36, the carriers being severally connected to this chain as hereinafter described so as to be moved thereby in the direction of the arrow X in Figs. 1, 2

and 4. One of the sprockets 36 may be driven by suitable connections, preferably such as are disclosed in the above Patent No. 1,700,425 or in my above application, Serial No. 476,776.

As preferably constructed, an individual winding carrier includes an upright plate-like por tion 60 adapted to bridge the distance between the rails 4 and 5 and provided at its lower end with a horizontal bracket (Fig. 3) havingstuds 101 and 101, projecting therefrom at opposite sides of rail 5, stud 101 carrying an antifriction roll 62 adapted to run on the side surface of rail 5.

At its upper end,- the vertical plate 60 may be integral with or attached to an upper head portion 65 of the carrier, for example, by bolts 64,

(Fig. 4). This head portion of the carrier is preferably arranged to have limited motion with respect to, and to be yieldingly urged toward the upper rail 4. Referring to Fig. 6, the head portion 65 of the carrier is preferably provided with a rearwardly projecting lug 102 above the rail 4 and having pivotally mounted thereon a link 103 carrying an anti-friction roll 104 adapted to bear against the inner face of rail 4. Link 103 is provided with a lug into which is hooked a tractor rod 105 extending through a bore 106 in the head portion of the carrier and surrounded in part by a spring 107, the tension of which is adjustable by a nut 108. The spring 107 yieldingly urges the roll 104 toward the head of the carrier and against the inner face of rail 4. Inward movement of the head portion thus induced may conveniently be limited by a pair of anti-friction rolls 109 (Figs. 3 and 6) positioned on the carrier to bear against the outer face of rail 4 to oppose the action of spring 107.

To enable the carrier to be moved about the machine by the chain 30, a lug 110 may be provided on the head portion of the carrier, this lug having pivotally mounted thereon a tractor link 111 inturn pivotally connected to a lateral extension 112 of one of the links of chain 30.

The strand material to be wound on the traveling winding carriermay be supplied from a wound bobbin B,preferably held by a pin 122 on a bracket 122 hinged on the upright 60 for automatic dumping by inversion, as explained in my copending application Serial No. 476,776. Instead, if desired, the winding instrumentalities of the present device may receive a strand from a spinning, twisting, drafting, feeding or other strand-manipulating device or source of supply, traveling with the carrier, for example as disclosed in my copending application Serial No. 508,868, now Patent No. 1,964,715, issued July 3, 1934.

It will be understood that the machine may include a large number of the traveling winding carriers such as are herein described; the machine may for example have eighty such carriers.

Upon the individual traveling carrier, and preferably upon its head portion 65, I provide means for holding awinding strand package for rotation, to wind up strand material coming from the supply, such holding means preferably taking the form of a live spindle 200, (Fig. 7) equipped with a collar 201 which is adapted to have driving engagement with the butt of a winding core on the spindle, the spindle 200 being mounted for rotation in ball bearings 202 at one end of a lever arm 204. Preferably the arm 204 is bifurcated at its opposite end, as shown in Fig. 4, to embrace a bearing-204* at the upper end of an upwardly extending platelike part 68 of the carrier head, to which it is pivotally mounted, as by-a pivot pin 73, Fig. 3.

My invention comprehends various types of means for rotating the winding package during travel thereof with the carrier; in; the form of mechanism of Figs. 1 to 10, such means by way of example includes elongated rotary tractor rolls 50, 51, extending along the straight portions of the guideway and rotatable at high speeds by any suitable driving connections-such as described in either of the above two patents and either of the above two applications. It will readily be understood how a winding strand package or spindle 200 may rest upon and be frictionally driven all of the winding packages contacting withrolls 50 and51 being thus rotated at the constant surface speed of these rolls.

As a substitute for direct frictional contact of the winding package and a driving tractor roll, one or more intermediate driving elements may be interposed; for example, Fig. 7 shows a wheel 207 fast on the live spindle 200 and carrying a tire 208 of friction material such as cork, rubber or the like, positioned frictionally to contact with the roll 50, as a consequence of which the live spindle and winding package. may be rotated at a constant angular velocity. The tire 208 may be of a diameter such as to remain in contact with the tractor roll 50 or 51 until the desired amount of strand has been wound on the winding package core. Upon the attainment of the diameter of the tire 208, the winding package itself engages the tractor roll 50 or 51 and is thereafter driven at a constant surface speed by direct frictional contact. The machine is therefore capable of simultaneously winding a large number of traveling packages,

which are of varying sizes due in part to starting of winding at different times, the packages of small diameter being rotated at constant angular velocity and the packages of larger diameter being rotated at constant surface speed. This mode of operation permits the package-driving tractor rolls 50 and 51 to be rotated at high speeds appropriate to the driving of large winding packages without causing unduly fast angular rates of rotation of the smallest diameter winding packages.

The traverse mechanism of the machine is such as will lay the winding strand on each of the winding packages in the form of alternately directed multi-turri spirals, that is, spirals which extend a plurality of turns around the package. Preferably the traverse mechanism includes an individual crossed-groove traverse cam adapted to travel with each of the winding package carriers, and providing a considerable range of traverse such as is required in winding a cheese or cone of considerable axial length. A preferred form of such traverse mechanism will first be described, following which will be described the mechanism by which the speed of traverse is related to the speed of winding.

Preferred form of traverse. device being suited to lay the strand in a similar pat tern on the winding package.

Referring to Figs. 3 and 8, a polished steel bar 150 of triangular section is fixed at its opposite ends in the plates 66 and 67 and forms a slideway for a traverse guide slider 151. As shown in Figs. 8 and 9, this slider includes a sheet metal'sleeve 152 shaped to fit the slideway 150, and carrying a light tube 153 which is bored pivotally to receive a pin 154 projecting from the middle of a cam follower 156. By virtue of engagement of the follower 156 with the groove about the center 73 on the are T (Figs. 3 and 70 of the cam 70, rotation of the cam rapidly reciprocates the sleeve 152.

As explained above, the construction of the holder for the winding package maybe such that the package is first driven through the intermediary wf the tire 208 which is larger than the momentary diameter of the winding package. This implies that during such driving, the point of contact of the winding strand and package periphery will move materially, (in the present construction, toward the surface of the tractor rcll 50 or 51). It is desirable that the traverse device guide the strand close to such point of contact at all times, to insure accuracy of strand distribution on the package. The slider sleeve 152 is preferably provided with a traverse guide having a strand-guiding portion capable of running on the surface of the package at all diameters oi the latter. As shown in Figs. 8, 9 and 10, such a guide 160 is,preferably of sheet material bent into a trough-like contour to provide a central strand passage 161 which converges toward the winding package, the guide being pivotally retained by bent-over ears, 163, which embrace and turn on a C-shaped pivot member 164 carried by the slider 152. A leaf spring 166 bearing on the top of slider 152, extending under the c-shaped pivot member 164 and then pressing upwardly against the under side of the guide 160, serves yieldingly to retain the free end of the guide in contact with the winding package periphery. The lateral edges of the strand guide 160 are bent down on a curve as illustrated at 160 (Fig. 9), the free end of the guide thus being capable of sliding smoothly back and forth in contact with the winding package at all diameters of the latter. The portions of the bent-down lateral edges 160 near the pivot point 164 are adapted, (regardless of the diameter of the winding package,) to plough up and place. within the trough-like strand passage 161, a strand running over a cover plate 110 or other suitable guide from the supply to the winding package. This arrangement comprises a preferred means for automatically threading the guide upon initiation or resumption of winding.

The traversing strand guide 160 is shown in full lines in Fig. 8 in its position initially assumed in laying a strand on a bare, or almost bare, core W. The dotted circle R of Fig. 8 which corresponds to the diameter of tire 208 indicates the diameter of the winding package when the package periphery attains contact with the drive roll 50; during the growth of the package to this diameter rotation of the package is induced by the driving action of the tire 208 and live spindle 200. As the package grows to this diameter (equal to that of tire 208, and such as to make contact with the rotary drive roll 50 or 51) the hinged or pivoted traverse guide 160 swings in the general direction of the drive roll, as shown by the arrow S (Fig. 8), eventually reaching its lower dotted position in Fig. 8 where the drive roll shields the traverse guide from further downward displacement by the winding 8). Such recession of the axis of spindle 200 is in a direction generally awayfrom the traverse guide 160 but is followed .by the traverse guide. The traverse guide 160 during winding of a package thus moves successively in two generally opposite directions in maintaining contact with or conforming to the package periphery. As a consequence of these arrangements the amplitude of such conforming movement of the guide is diminshed over that which would be required if all of its conforming movement were in a single direction. The traversing mechanism is thus enabled to be very compact, the

space allowed for movement of the hinged tra erse guide 160 may be small, and the length of the traverse guide may be short, without materially limiting the diameter of packages to be wound. "The use of a spring to hold the traverse guide against the winding package of necessity causes the guide to bear against the package with different pressures which depend on the displacement of the guide; these difierences are minimized by having the amplitude of displacement of the traverse guide small, as described.

The point of tangency of the winding package and the drive roll 50 or 51 will be determined by the intersection with their circumferences of a line N connecting the center of the winding spindle and the center of the drive roll. The locus T of positions of the spindle 200 is so disposed with relation to the center of the drive roll that this point of tangency gradually moves in a counterclockwise direction on the roll periphery and away from the traverse guide 160 and other traversing mechanism. This insures that growth of the package beyond a diameter such for example as R will not further displace the traverse guide and particularly will not interfere with the pivot point 164 of the traverse guide. This pivot point 164 may in this improved construction, be so close to the initial point of tangency as to interfere with a large size package should the package not be moved, asdescribed, circumferentially with respect to the drive roll. The exact extent of movement of the point of tangency peripherally on roll 50 will depend upon the effective length of the packagecarrying arm 204, which may be adjusted. The construction line V of Fig. 8 connects the axis of spindle 200 and the center 73 about which arm 204 swings; at initial contact of the winding package and drive roll, the angle a between this line V and the above-described line N will be greater than as shown.

As the package grows to diameters larger than the diameter R, the efiect of the shifting of the point of tangency, (partially ofiset'by the countervailing effect of straightening of the arc of the package periphery) is to cause a recession of the package periphery which is followed by the traverse guide 160. The dotted line U (Fig. 8) indicates one larger diameter of the package, and the area intercepted between the diameters R and U in Fig. 8 represents a recession of a portion of the package periphery from the traverse slide 152, pivot memberv 164, and associated parts, during growth of the package to a circumference such as is indicated by the are U. The traverse guide being yieldingly urged into contact with the package, will follow, and will assume for the diameter U the intermediate dotted-line position, touching this diameter.

While particularly adapted for use in conjunction with a,winding package which is wound to a predetermined diameter by means of a live spindle before contacting with a rotary friction drive roll, the means for circumferentially shifting the point of tangency of package and drive roll in combination with the traverse guide capable of maintaining contact with the receding package periphery, is of utility also in cases wherein a winding package contacts with the drive roll at the outset. By way of illustration, assuming for the moment that the circle R now represents the circumference of a winding package core adapted to be initially rotated by the drive roll, (the parts then being on an enlarged scale), the traverse guide 160 is capable of moving in the same manner as described above from its lower dotted position, to positions such as the intermediate dotted position always in contact with the winding package as the latter grows; at the same time the winding package is shifted circumferentially at the drive '-roll to an extent suflicient to prevent interference with the traverse mechanism.

The traverse guide is in each case capable of accurately laying the strand on the package by virtue of its continually running on the package periphery. Furthermore the traversing mechanism can be, as illustrated, very compact and hence well adapted to operate at high speed.

In the class of textile machines wherein a strand is wound on a package during travel of the package in relation to the machine, my invention provides for traversing the winding strand by a member which maintains contact with the periphery of the traveling package and guides the strand at the point where the latter goes onto the package; this is deemed to be a distinct advantage in insuring accuracy of disposition of the wound strands. Particularly this arrangement prevents the strand from lagging behind the traverse guide, and by preventing such undesired phenomena, permits the guide to lay the strand in rather sharp welldefined cusps which correspond in position to the end of the travel of the guide. As a result, the package will be formed with a length closely approximating the length of travel of the guide, instead of considerably shorter, as in machines where the strand-guiding element is spaced from the winding package.

Mechanism 101' relating the speeds of traverse and winding For suitably synchronizing or relating the speeds of strand traverse and of winding rota-- tion of the traveling packages, mechanism is provided for causing the linear rate of strand traverse (e. g. the reciprocatory speed of the guide or eye 160) to bear a constant ratio to the angular rate of rotation of the winding package as the package grows. Conversely, the

effect of this means is to cause the ratio between the linear rate of traverse to diminish with respect to the surface speed of the winding package as the package grows. Advantageously, with the above described individual traverse devices on the individual winding carrier units, the mechanism for thus relating the speeds of traverse and winding may take the the machine. Such articulated connections may comprise as shown for example in Fig. 3, a pulley 170 fast on the winding spindle 200, a

belt 171 leading therefrom to an idler double grooved pulley 172 coaxial with the pivot of the arm 204, a pulley 174 fast to the traverse cam 70, and a second belt connecting this pulley to the idler pulley 172. The action of these connections, constituted of belts and pulleys, is to cause the rotation of the traverse cam and winding package to be at directly proportional velocities for various diameters of the winding package, and as a consequence to cause the frequency of oscillation of the traverse guide 160 to bear a constant ratio to the angular velocity of the winding package.

In this instance, such desired ratio is obtained by driving the traverse device through the described belt and pulley connections. Ob-

viously if the speed ratio of the above described belt and pulley connections is such that the -winding package makes an integral number of revolutions while the traverse guide 160 makes one complete back and forth oscillation, each spiral portion of wound strand will be laid approximately radially on top of the last preceding like spiral portion. Such relationship of the spiral portions of wound strand (sometimes called ribbon wind) would present certain disadvantages in most winding operations, and my copending application, Serial No. 477,776, explains mechanism for preventing the occurrence of this condition in the several carriers of a traveling winding machine. In the present traveling winding machine, however, the phenomena of exact radialcoincidence of successive like spirals may be effectively prevented without such special mechanism, merely by the establishment of the proper speed ratio between the motions of the winding package and the traverse guide. If this speed ratio between thewinding package makes a plurality of revolu-- tions plus or minus a small fraction of a revolution, it will be assured that each spiral portion of the wound strand will lie alongside the preceding like spiral portion; preferably the connections constituted of belts 171 and 173 and pulleys 170, 172 and 174 provide in the aggregate such a ratio between the speeds of the package and the traverse guide.

Fig. 11 shows a typical wound package which may be produced during travel about a machine of the present invention, the package being illustrated as partly broken away to disclose the configuration of an inner small diameter layer. Consideration of the left-hand end of this figure will indicate that the end face of the package may be constituted of the cusps c which connect oppositely disposed spiral portions of the strand; the cusps 0 lie in regular progression circumferentially of the package. A comparison of large and small diameter layers of the package will disclose the fact that the cusps c are more acute in the small diameter layer and less acute in the large diameterlayer, and further that the inclination of the strandwith respect to the axis of the package is greater in the large dipackage and the speed of thetraver'se guide, as the package grows. A- machine engaged in making the'wound package of Fig. 11 will have its ratio of angular velocity of winding package to speed of oscillation of its traverse guide such that for each complete back and forth oscillation of the traverse guide the winding package will make six revolutions plus or minus a very small fraction of a revolution suflicient'to accommodate one thickness of the spirally inclined wound strand. Thus, each spiral-wound portion will ,lie close beside the preceding like spiral wound portion. Fig. 12 illustrates a part of a similar package having a more open winding.. In the winding rotation of this package during one oscillation of the traverse guide, the fraction of a revolution by which the number of revolutions of the package di fiers from an integral number is somewhat larger than in the case of the package of Fig. 11. The package of Fig. 12 is, like that of Fig. 11, characterized by approximate parallelism of successive like spiral wound portions, and by the occurrence of such spiral portions in regular order at approximately the same peripheral distance apart.

Preferably means is provided for adjusting the ratio between the angular velocity of the package and the speed of the traverse guide, thus to wind close-wound packages like that of Fig. 11 from diiferent weights of yarn, or to provide various degrees of spacing of the like spiral wound portions to form packages like that of Fig. 12 with more or less open patterns of winding.

In the present instance such adjusting means is.

tween angular velocity of the winding package and speed of the traverse guide. I

A specific instance of the operation of a machine such as described will now be apparent. The various traveling winding carriers of the machine are moved in procession along the rails 4 and 5 by the action of the chain 30. The winding packages of these carriers which are at the time opposite to one of the tractor rolls 50 or 51 are subjected to winding rotation,

(while of small diameter by frictional contact of the corresponding tire 208 with the tractor roll, and later when of appropriate larger diameter by the direct frictional engagement of the package and tractor roll.) The traverse instrumentalities of the machine distribute the winding strands on the several traveling winding packages in overlapped layers of reversed spiral windings by traverse of the strands at rates which are proportional to the angular velocities of the respective packages throughout their growth.

The modified form of traveling carrierof Figs. 13, 14 and 15 includes many of the features and specific instrumentalities of the carrier just described; the description of all of these will not be repeated. Corresponding parts are designated by the same reference characters in the figures of drawings illustrative of both forms. of the carrier.

With the carrier of Figs 13, 14 and 15, the two tractor rolls 50 and 51 (Figs. 1, 2 and 3) are omitted, and the rotation of the winding package and operation of the traverse device therefor are effected by an electric motor M, preferably mounted on the side plate 67 of the carrier head and connected directly to drive the traverse cam 70. From the traverse cam, an articulated connection preferably comprising the previously described pulleys 170, 172 and 174 and belts 171 and 173 serves to rotate the live spindle 200 which carries the winding package core 10. The ratio between the angular velocity of the winding package and the speed of the traverse guide is in this case preferably constant as in the previously described form of carrier; thus the same kind of wound package is produced. For supplying current to the individual motors of the several carriers of a machine, the machine frame may carry conductor rails 40, 41 and 42, (Figs. 2 and 13) adapted to supply current to brushes 112, 113 and 114 on the individual carriers, the brushes of a carrier being connected to the motor M of the carrier by suitable electrical connections. The

rotation of winding strand packages and operation of traverse devices by motors adapted to travel in a predetermined path about the machine with the strands being manipulated is more particularly described and claimed in my said Patent No. 1,964,715. 7

It will be observed that rotation of the live spindle .200 rotates the winding package by the application of torque to the interior of the package while the traversing strand is drawn onto and distributed on' the package. Preferably means is provided for maintaining a compressive force on the periphery of the package during this winding. Preferably this pressure is applied by a press roll 209 adapted to turn with the package, and conveniently pivotally mounted in brackets 210 in position to support the growing package.

In the carrier. of Figs. 13, 14 and 15, the hinged traverse guide of the previously described form of device may conveniently be replaced by a simpler form of guide, such-for example as that disclosed in my copending application Serial No. 476,776.

Referring to Fig. 16, the guide rod upon whichthe slider moves may be square in crosssection. The slider 151 may conveniently comprise a light metal casting having a square opening at 151 for a slide bearing on the rod 150 and provided with a vertical lug 151 bored to receive the pin 154 which projects from the cam follower 156 Integral with the slider casting is a yarn guide 160 having lateral cam slopes 160 and a central yarn notch 160.

Both forms of carrier may winding of cylindrical or conical packages as desired by providing for adjustment of the pivoted arm 204 so as'either to level or incline the spindle 200 or analogous package holder. Such adjustment may be provided for byforming the pivoted arm in two parts 204 and 204 ,--the outer part 204 which holds the spindle bearing being rotatable with respect to the inner part 204 and being normally held fixed thereto by a bolt 204 -as described in my copending application, Serial No. 477,776.

The winding carriers of the present invention may be provided with suitable tension, slubcatching and stop-motion devices, which may be those described 'in the patent of E. J. and W. G. Abbott, No. 1,700,425, but which preferably are those disclosed and claimed in my copending applications, Serial No. 476,776, Serial 7! No. 484,993, now Patent No. 1,905,259, issued April .tively,

be adapted for the 25, 1933 and said Patent No. 1,964,715, the stopmotion mechanism of my said Patent No. 1,964,- 715 being particularly suited for stopping the individual electric motor M of Figs. 13, 14 and 15 of the present application. .The tension device illustrated in Figs. 3, 4 and-5 is described and claimed in my copending application, Serial No. 476,776.

Both forms of traveling winding carriers of the present invention are illustrated as equipped with means, for shifting the winding package away from its normal winding position, for instance to present it for more ready attention by an operator, for doffing, uniting of broken yarn ends or the like, or in the form of Figs. 3 to 9 for stopping driving of the package by the tractor roll, or in the form of Figs. 13, 14 and 15 for actuating a stop-motion switch by movement of the package holding parts as described in my copending application Serial No. 476,776, and said Patent No. 1,964,715. Such means typically includes a lifter rod 301 connected at its top to a fork in the pivoted arm 204, a crank 300 connected to the bottom of the lifter rod and itself fast on a shaft 303, and a dog 304 pivotally mounted at 316 on the shaft 303. Contact of the dog 304 with an abutment such as a pin 307 extending from the rail 4 results in the dog being detained and turned, the shaft 303 and crank 300 being turnedand the lifter rod 301 being raised to swing the arm 204 to its upper position as shown in Fig. 5. Subsequent contact of the dog 304 with an upper pin 320 (Fig. 5) results in these parts moving in the reverse direction to restore the package to its normal winding position.

These operations may take place at the end of a straight portion of the guideway and at the beginning of the next straight portion, respec or the operation of raising of the package may take place at any point at which .a suitable detector feeler 310 permits the dog to contact with a pin on the rail 4, as fully explained in my copending applications Serial Nos. 476,776,

. 518,433, now Patent No. 1,968,747, issued July 31, 1934 and said Patent 1,964,715. In any event the shifting-of the package is accommodated by the articulated driving and controlling connection between the spindle 200 and the traverse cam, without loss of connection between these parts.

It should be understood that the present disclosure is for the purpose of illustration only and that this invention includes all modifications and equivalents which fall within the scope of the appended claims.
